Windows 2K3 and Virtual Server 2005 guests NAT problem



Hi everyone,
I am forced to post on not finding a suitable applicable solution from
the various permutations of the same issue.
we are developing some test applications on guest machines that run on
Virtual Server. However, these machines are not able to connect to our
corporate LAN. I had enabled the Loopback adapter to form a virtual
internal network.

The server is essentially connected to a 'public' network and a
private network.

Server --> NIC1 --> (LAN)
--> NIC2(LoopbackAdapter) --> Guest OS

Notes :
1. The client is able to ping the internal address of the server
"192.168.1.55" ..
2. Pinging any external address, or name resolution does not happen on
the client.
3. The NAT/Firewall setting on the server is configured to provide
both DHCP and DNS. But only DHCP seems to be working.

Can you give me any clues as to how I can get the client to connect to
ip addresses on the corporate LAN ?
